Programs & Examples On #Sizzle

To get all the elements starting with "jander" you should use:

$("[id^=jander]")

To get those that end with "jander"

$("[id$=jander]")

See also the JQuery documentation

select @currentTerm = CurrentTerm, @termID = TermID, @endDate = EndDate
    from table1
    where IsCurrent = 1

Winmerge has a command line utility that might be worth checking out.

Also, you can use the graphical part of it too depending on what you need.

Above solution does not work for me , I have tried following and it is working in all browsers.

simply made a fake ajax call, it will make a entry into referer header.

var request;
if (window.XMLHttpRequest) { // Mozilla, Safari, ...
    request = new XMLHttpRequest();
} else if (window.ActiveXObject) { // IE
    try {
        request = new ActiveXObject('Msxml2.XMLHTTP');
    } catch (e) {
        try {
            request = new ActiveXObject('Microsoft.XMLHTTP');
        } catch (e) {}
    }
}
request.open("GET", url, true);
request.send();

Much like leonardocsouza, I had the same problem. To clarify a bit, this is what my folder structure looked like when I ran node server.js

node_modules/
app/
  index.html
  server.js

After printing out the __dirname path, I realized that the __dirname path was where my server was running (app/).

So, the answer to your question is this:

If your server.js file is in the same folder as the files you are trying to render, then

app.use( express.static( path.join( application_root, 'site') ) );

should actually be

app.use(express.static(application_root));

The only time you would want to use the original syntax that you had would be if you had a folder tree like so:

app/
  index.html
node_modules
server.js

where index.html is in the app/ directory, whereas server.js is in the root directory (i.e. the same level as the app/ directory).

Side note: Intead of calling the path utility, you can use the syntax application_root + 'site' to join a path.

Overall, your code could look like:

// Module dependencies.
var application_root = __dirname,
express = require( 'express' ), //Web framework
mongoose = require( 'mongoose' ); //MongoDB integration

//Create server
var app = express();

// Configure server
app.configure( function() {

    //Don't change anything here...

    //Where to serve static content
    app.use( express.static( application_root ) );

    //Nothing changes here either...
});

//Start server --- No changes made here
var port = 5000;
app.listen( port, function() {
    console.log( 'Express server listening on port %d in %s mode', port, app.settings.env );
});

Change the signature of the CreateFile method to expect a SupportedPermissions value instead of plain Enum.

public string CreateFile(string id, string name, string description, SupportedPermissions supportedPermissions)
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = supportedPermissions
    };

    return file.Id;
}

Then when you call your method you pass the SupportedPermissions value to your method

  var basicFile = CreateFile(myId, myName, myDescription, SupportedPermissions.basic);

I've been working through this entire post and others as well as tutorial videos without being able to solve my problem of not receiving messages, the registration token however worked.

Until then I had only been testing the app on the emulator. After trying it on a physical phone it instantly worked without any prior changes to the project.

My approach:

• define a default constraint on the ModDate column with a value of GETDATE() - this handles the INSERT case

• have a AFTER UPDATE trigger to update the ModDate column

Something like:

CREATE TRIGGER trg_UpdateTimeEntry
ON dbo.TimeEntry
AFTER UPDATE
AS
    UPDATE dbo.TimeEntry
    SET ModDate = GETDATE()
    WHERE ID IN (SELECT DISTINCT ID FROM Inserted)

Although this question has an accepted answer but I think this is a much cleaner way to achieve the desired output

<select required>
<option value="">Select</option>
<option>English</option>
<option>Spanish</option>
</select>

The required attribute in makes it mandatory to select an option from the list.

value="" inside the option tag combined with the required attribute in select tag makes selection of 'Select' option not permissible, thus achieving the required output

The working solution for Integer number to binary conversion is below.

int main()
{
    int num=241; //Assuming 16 bit integer
    for(int i=15; i>=0; i--) cout<<((num >> i) & 1);
    cout<<endl;
    for(int i=0; i<16; i++) cout<<((num >> i) & 1);
    cout<<endl;
    return 0;
}

You can capture the cout<< part based on your own requirement.

As long as you do not allow NULL for a value, they should be handled the same, but the value NULL is handled differently on databases(AFAIK MS-SQL do not allow more than one(1) NULL value, mySQL and Oracle allow this, if a column is UNIQUE) So you must define this column NOT NULL UNIQUE INDEX

For copy directory use following command

cp -r source    Destination

For example

cp -r  /home/hasan   /opt 

For copy file use command without -r

cp   /home/file    /home/hasan/

You could also rewrite the code to remove the nested 'If' statement completely.

INSERT INTO @Classes    
SELECT XXXXXX      
FROM XXXX 
Where @Term = 3   

---- **always** "fall thru" to here, no matter what @Term is equal to - always do
---- the following INSERT for all elementary schools    
INSERT INTO @Classes        
SELECT    XXXXXXXX        
FROM XXXXXX (more code) 

As pointed in Vlad's answer, you are running out of free color slots. One way to get around that would be to cache the colors: whenever you try a RGB combination, the routine should first check if the combination is in the cache; if it is in the cache, then it should use that one instead of creating a new one from scratch; new colors would then only be created if they're not yet in cache.

Here's the implementation I use; it uses XSSF plus Guava's LoadingCache and is geared towards generationg XSSF colors from CSS rgb(r, g, b) declarations, but it should be relatively trivial to adapt it to HSSF:

    private final LoadingCache<String, XSSFColor> colorsFromCSS = CacheBuilder.newBuilder()
            .build(new CacheLoader<String, XSSFColor>() {

                private final Pattern RGB = Pattern.compile("rgb\\(\\s*(\\d+)\\s*, \\s*(\\d+)\\s*,\\s*(\\d+)\\s*\\)");

                @Override
                public XSSFColor load(String style) throws Exception {
                    Matcher mat = RGB.matcher(style);
                    if (!mat.find()) {
                        throw new IllegalStateException("Couldn't read CSS color: " + style);
                    }                       
                    return new XSSFColor(new java.awt.Color(
                            Integer.parseInt(mat.group(1)), 
                            Integer.parseInt(mat.group(2)), 
                            Integer.parseInt(mat.group(3))));
                }

            });

Perhaps someone else could post a HSSF equivalent? ;)

If your DBMS supports the notation, you need a separate set of parentheses for each row:

INSERT INTO Data(Col1) VALUES ('Hello'), ('World');

The cross-referenced question shows examples for inserting into two columns.

Alternatively, every SQL DBMS supports the notation using separate statements, one for each row to be inserted:

INSERT INTO Data (Col1) VALUES ('Hello');
INSERT INTO Data (Col1) VALUES ('World');

If the types can be directly cast this is the cleanest way to do it:

var target = yourList.ConvertAll(x => (TargetType)x);

If the types can't be directly cast then you can map the properties from the orginal type to the target type.

var target = yourList.ConvertAll(x => new TargetType { SomeValue = x.SomeValue });

int index= datagridview.rows.add();
datagridview.rows[index].cells[1].value=1;
datagridview.rows[index].cells[2].value="a";
datagridview.rows[index].cells[3].value="b";

hope this help! :)

While you can set the locale exporting an env variable, you will have to do that every time you start a session. Setting a locale this way will solve the problem permanently:

sudo apt-get install locales
sudo locale-gen en_US.UTF-8
sudo echo "LANG=en_US.UTF-8" > /etc/default/locale

In most recent version of Rails (can't tell which one exactly though), you could use the as_json method :

@post = Post.first
hash = @post.as_json
puts hash.pretty_inspect

Will output :

{ 
  :name => "test",
  :post_number => 20,
  :active => true
}

To go a bit further, you could override that method in order to customize the way your attributes appear, by doing something like this :

class Post < ActiveRecord::Base
  def as_json(*args)
    {
      :name => "My name is '#{self.name}'",
      :post_number => "Post ##{self.post_number}",
    }
  end
end

Then, with the same instance as above, will output :

{ 
  :name => "My name is 'test'",
  :post_number => "Post #20"
}

This of course means you have to explicitly specify which attributes must appear.

Hope this helps.

There are many links that lets you know how to handle post values from checkboxes in php. Look at this link: http://www.html-form-guide.com/php-form/php-form-checkbox.html

Single check box

HTML code:

<form action="checkbox-form.php" method="post">
    Do you need wheelchair access?
    <input type="checkbox" name="formWheelchair" value="Yes" />
    <input type="submit" name="formSubmit" value="Submit" />
</form>

PHP Code:

<?php

if (isset($_POST['formWheelchair']) && $_POST['formWheelchair'] == 'Yes') 
{
    echo "Need wheelchair access.";
}
else
{
    echo "Do not Need wheelchair access.";
}    

?>

Check box group

<form action="checkbox-form.php" method="post">
    Which buildings do you want access to?<br />
    <input type="checkbox" name="formDoor[]" value="A" />Acorn Building<br />
    <input type="checkbox" name="formDoor[]" value="B" />Brown Hall<br />

  } 
  else
  {
    $N = count($aDoor);

    echo("You selected $N door(s): ");

It's Really Simple Just go to your styles.xml change the parent Theme to either Theme.AppCompat.Light.NoActionBar or Theme.AppCompat.NoActionbar and you are done.. :)

I spent an entire day bashing my head against this, the solution turned out to be simple..

R isn't zero-index.

Every programming language that I've used before has it's data start at 0, R starts at 1. The result is an off-by-one error but in the opposite direction of the usual. going out of bounds on a data structure returns null and comparing null in an if statement gives the argument is of length zero error. The confusion started because the dataset doesn't contain any null, and starting at position [0] like any other pgramming language turned out to be out of bounds.

Perhaps starting at 1 makes more sense to people with no programming experience (the target market for R?) but for a programmer is a real head scratcher if you're unaware of this.

If you prefer to use Query Builder instead of Eloquent here is the solutions

$result = DB::table('user')->where('name',=,'Jhon')->get();

First Solution

$array = (array) $result;

Second Solution

$array = get_object_vars($result);

Third Solution

$array = json_decode(json_encode($result), true);

hope it may help

The issue was indeed in package-lock.json, and after replacing it with a working version from another branch it worked.

What's interesting is seeing the diff:

So there really is some integrity checksum in the package-lock.json to verify that the file you are downloading hasn't been tampered with. It's just that somehow the integrity checksum was replaced in our package-lock.json with a SHA1 instead of a SHA-512 checksum. I have no idea how this happened.

In case you don't have a working version in another branch. Consider the message

npm ERR! code EINTEGRITY
npm ERR!

The best presentation for code in documents is in a fixed-width font (as it should appear in an IDE), with either a faint, shaded background or a light border to distinguish the block from other text.

A super quick and handy fix is to abuse Visual Studio's incredible intellisense by temporarily referencing the class somewhere.

Example:

System.Runtime.CompilerServices.ExtensionAttribute x = null;

When building or hovering the cursor over the line you can view the following error:

'System.Runtime.CompilerServices.ExtensionAttribute' exists in both 'C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5\System.Core.dll'

This tells you the two sources causing the conflict immediately.

System.Core.dll is the .dll file that you want to keep, so delete the other one.

I found mine sitting in the bin directory, but it may be elsewhere in the project.

As a matter of fact this is worth bearing in mind, because since the bin directory might not be included as part of the TFS change-set, it can explain why checking in your changes doesn't resolve the issue for other members of your team.

A suggestion for you - you can use parameter expansion to remove the part of the name from the last underscore onwards, and similarly at the start:

f=001_abc_0za.jpg
work=${f%_*}
name=${work#*_}

Then name will have the value abc.

See Apple developer docs, search forward for 'Parameter Expansion'.

There have been som changes to how we define the KeyboardWillHideNotification.

This solution works with Swift 4.2:

NotificationCenter.default.addObserver(self, selector: #selector(ViewController.keyboardWillShow), name: UIResponder.keyboardWillShowNotification, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(ViewController.keyboardWillHide), name: UIResponder.keyboardWillHideNotification, object: nil)


@objc func keyboardWillShow(_ notification:Notification) {
    if let keyboardSize = (notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
        self.view.frame.origin.y -= keyboardSize.height
    }
}

@objc func keyboardWillHide(_ notification:Notification) {
    if let keyboardSize = (notification.userInfo?[UIResponder.keyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
        self.view.frame.origin.y += keyboardSize.height
    }
}

The answer is very simple, there is a dissertation written by Roy Fielding.]1 In that dissertation he defines the REST principles. If an application fulfills all of those principles, then that is a REST application.

The term RESTful was created because ppl exhausted the word REST by calling their non-REST application as REST. After that the term RESTful was exhausted as well. Nowadays we are talking about Web APIs and Hypermedia APIs, because the most of the so called REST applications did not fulfill the HATEOAS part of the uniform interface constraint.

The REST constraints are the following:

1. client-server architecture

   So it does not work with for example PUB/SUB sockets, it is based on REQ/REP.

2. stateless communication

   So the server does not maintain the states of the clients. This means that you cannot use server a side session storage and you have to authenticate every request. Your clients possibly send basic auth headers through an encrypted connection. (By large applications it is hard to maintain many sessions.)

3. usage of cache if you can

   So you don't have to serve the same requests again and again.

4. uniform interface as common contract between client and server

   The contract between the client and the server is not maintained by the server. In other words the client must be decoupled from the implementation of the service. You can reach this state by using standard solutions, like the IRI (URI) standard to identify resources, the HTTP standard to exchange messages, standard MIME types to describe the body serialization format, metadata (possibly RDF vocabs, microformats, etc.) to describe the semantics of different parts of the message body. To decouple the IRI structure from the client, you have to send hyperlinks to the clients in hypermedia formats like (HTML, JSON-LD, HAL, etc.). So a client can use the metadata (possibly link relations, RDF vocabs) assigned to the hyperlinks to navigate the state machine of the application through the proper state transitions in order to achieve its current goal.

   For example when a client wants to send an order to a webshop, then it have to check the hyperlinks in the responses sent by the webshop. By checking the links it founds one described with the http://schema.org/OrderAction. The client know the schema.org vocab, so it understands that by activating this hyperlink it will send the order. So it activates the hyperlink and sends a POST https://example.com/api/v1/order message with the proper body. After that the service processes the message and responds with the result having the proper HTTP status header, for example 201 - created by success. To annotate messages with detailed metadata the standard solution to use an RDF format, for example JSON-LD with a REST vocab, for example Hydra and domain specific vocabs like schema.org or any other linked data vocab and maybe a custom application specific vocab if needed. Now this is not easy, that's why most ppl use HAL and other simple formats which usually provide only a REST vocab, but no linked data support.

5. build a layered system to increase scalability

   The REST system is composed of hierarchical layers. Each layer contains components which use the services of components which are in the next layer below. So you can add new layers and components effortless.

   For example there is a client layer which contains the clients and below that there is a service layer which contains a single service. Now you can add a client side cache between them. After that you can add another service instance and a load balancer, and so on... The client code and the service code won't change.

6. code on demand to extend client functionality

   This constraint is optional. For example you can send a parser for a specific media type to the client, and so on... In order to do this you might need a standard plugin loader system in the client, or your client will be coupled to the plugin loader solution.

REST constraints result a highly scalable system in where the clients are decoupled from the implementations of the services. So the clients can be reusable, general just like the browsers on the web. The clients and the services share the same standards and vocabs, so they can understand each other despite the fact that the client does not know the implementation details of the service. This makes possible to create automated clients which can find and utilize REST services to achieve their goals. In long term these clients can communicate to each other and trust each other with tasks, just like humans do. If we add learning patterns to such clients, then the result will be one or more AI using the web of machines instead of a single server park. So at the end the dream of Berners Lee: the semantic web and the artificial intelligence will be reality. So in 2030 we end up terminated by the Skynet. Until then ... ;-)

I am using a class that just uses one of the above methods behind the scenes... I noticed it works on Windows and Linux... I like using it though because it's easier to type clear() instead of system('clear') or os.system('clear')

pip3 install clear-screen

from clear_screen import clear

and then when you want to clear the shell:

clear()

You need to consider the case where the user presses enter in the middle of the text, not just at the end. I'd suggest detecting the enter key in the keyup event, as suggested, and use a regular expression to ensure the value is as you require:

<textarea id="t" rows="4" cols="80"></textarea>
<script type="text/javascript">
    function formatTextArea(textArea) {
        textArea.value = textArea.value.replace(/(^|\r\n|\n)([^*]|$)/g, "$1*$2");
    }

    window.onload = function() {
        var textArea = document.getElementById("t");
        textArea.onkeyup = function(evt) {
            evt = evt || window.event;

            if (evt.keyCode == 13) {
                formatTextArea(this);
            }
        };
    };
</script>

If you need to loop inside a directory recursively for a particular kind of file, use the below command, which filters all the files of doc file type

$fileNames = Get-ChildItem -Path $scriptPath -Recurse -Include *.doc

If you need to do the filteration on multiple types, use the below command.

$fileNames = Get-ChildItem -Path $scriptPath -Recurse -Include *.doc,*.pdf

Now $fileNames variable act as an array from which you can loop and apply your business logic.

I faced a similar problem. The problem in my case was, Number of rows in X was not equal to number of rows in y.

i.e. number of entries in feature columns was not equal to number of entires in target variable since I had dropped some rows from freature columns.

If your designated icon shows when you run the EXE but not when you run it from Visual Studio, then, for a WPF project add the following at the top of your XAML: Icon="Images\MyIcon.ico". Put this just where you have the Title, and xmlns definitions. (Assuming you have an Images folder in your project, and that you added MyIcon.ico there).

Generic extension method (Gets Min and Max in one iteration):

public static class MyExtension
{
    public static (T Min, T Max) MinMax<T>(this IEnumerable<T> source) where T : IComparable<T>
    {
        if (source == null)
        {
            throw new ArgumentNullException(nameof(source));
        }

        T min = source.FirstOrDefault();
        T max = source.FirstOrDefault();

        foreach (T item in source)
        {
            if (item.CompareTo(min) == -1)
            {
                min = item;
            }
            if (item.CompareTo(max) == 1)
            {
                max = item;
            }
        }

        return (Min: min, Max: max);
    }

}

This code used C# 7 Tuple

Constant initializer allowed by C++ Standard only for integral or enumeration types. See 9.4.2/4 for details:

If a static data member is of const integral or const enumeration type, its declaration in the class definition can specify a constant-initializer which shall be an integral constant expression (5.19). In that case, the member can appear in integral constant expressions. The member shall still be defined in a name- space scope if it is used in the program and the namespace scope definition shall not contain an initializer.

And 9.4.2/7:

Static data members are initialized and destroyed exactly like non-local objects (3.6.2, 3.6.3).

So you should write somewhere in cpp file:

const char* SomeClass::SOMETHING = "sommething";

', '.join(set_3)

The join is a string method, not a set method.

You can always use an attribute selector. The selector itself would look something like:

a[data-item-id=stand-out]

function millisecondsToTime(millisecs){
  var ms = Math.abs(millisecs) % 1000;
  var secs = (millisecs < 0 ? -1 : 1) * ((Math.abs(millisecs) - ms) / 1000);
  ms = '' + ms;
  ms = '000'.substring(ms.length) + ms;
  return secsToTime(secs) + '.' + ms;
}

version for data.table based on code from dmanuge :

convNumValues<-function(ds){
  ds<-data.table(ds)
  dsnum<-data.table(data.matrix(ds))
  num_cols <- sapply(dsnum,function(x){mean(as.numeric(is.na(x)))<0.5})
  nds <- data.table(  dsnum[, .SD, .SDcols=attributes(num_cols)$names[which(num_cols)]]
                        ,ds[, .SD, .SDcols=attributes(num_cols)$names[which(!num_cols)]] )
return(nds)
}

$.each($("#MySelect option"), function(){
                    alert($(this).text() + " - " + $(this).val());

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    @Override
    public void onNewToken(String s) {
        super.onNewToken(s);
        Log.e("NEW_TOKEN",s);
    }

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);
    }
}

In .net, every instance of Object, or any type derived therefrom, includes a data structure which contains information about its type. "Real" value types in .net do not contain any such information. To allow data in value types to be manipulated by routines that expect to receive types derived from object, the system automatically defines for each value type a corresponding class type with the same members and fields. Boxing creates a new instances of this class type, copying the fields from a value type instance. Unboxing copies the fields from an instance of the class type to an instance of the value type. All of the class types which are created from value types are derived from the ironically named class ValueType (which, despite its name, is actually a reference type).

Bash does not support multidimensional arrays.

You can simulate it though by using indirect expansion:

#!/bin/bash
declare -a a0=(1 2 3 4)
declare -a a1=(5 6 7 8)
var="a1[1]"
echo ${!var}  # outputs 6

Assignments are also possible with this method:

let $var=55
echo ${a1[1]}  # outputs 55

Edit 1: To read such an array from a file, with each row on a line, and values delimited by space, use this:

idx=0
while read -a a$idx; do
    let idx++;
done </tmp/some_file

Edit 2: To declare and initialize a0..a3[0..4] to 0, you could run:

for i in {0..3}; do
    eval "declare -a a$i=( $(for j in {0..4}; do echo 0; done) )"
done

This SO thread will solve your problem. Solution in short:

$url = 'http://www.google.co.in/intl/en_com/images/srpr/logo1w.png';
$img = '/my/folder/my_image.gif';
file_put_contents($img, file_get_contents($url));

checked the program and the results are as,

p++;    // use it then move to next int position
++p;    // move to next int and then use it
++*p;   // increments the value by 1 then use it 
++(*p); // increments the value by 1 then use it
++*(p); // increments the value by 1 then use it
*p++;   // use the value of p then moves to next position
(*p)++; // use the value of p then increment the value
*(p)++; // use the value of p then moves to next position
*++p;   // moves to the next int location then use that value
*(++p); // moves to next location then use that value

This works best for me, especially when using dotnet core single file publish. Path.GetDirectoryName(System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName).

Simple and quick:

Dim lastRow as long
Range("A1").select
lastRow = Cells.Find("*",SearchOrder:=xlByRows,SearchDirection:=xlPrevious).Row

Example use:

cells(lastRow,1)="Ultima Linha, Last Row. Youpi!!!!"

'or 

Range("A" & lastRow).Value = "FIM, THE END"

Unfortunately: NO.

We're all eagerly awaiting the Java support for extension methods

Since the splitting on commas question is duplicated to this question, adding this here.

If you want to split on a character and also handle extra whitespace that might follow that character, which often happens with commas, you can use replace then split, like this:

var items = string.replace(/,\s+/, ",").split(',')

If you can safely make (firstName, lastName) the PRIMARY KEY or at least put a UNIQUE key on them, then you could do this:

INSERT INTO logins (firstName, lastName, logins) VALUES ('Steve', 'Smith', 1)
ON DUPLICATE KEY UPDATE logins = logins + 1;

If you can't do that, then you'd have to fetch whatever that primary key is first, so I don't think you could achieve what you want in one query.

You can always try putting this code in your main css without modifying the bootstrap file what is most recommended so you keep consistency if in a future you update the bootstrap file.

.tooltip-inner {
background-color: #FF0000;
}

.tooltip.right .tooltip-arrow {
border-right: 5px solid #FF0000;

}

Notice that this example is for a right tooltip. The tooltip-inner property changes the tooltip BG color, the other one changes the arrow color.

As I understood in normal cases we are creating a table with Primary key which is having Identity property
So Rename or Delete a column which is associated with Primary Key constraint will not be possible because constraint Rules are validating column structure.
Tto achieve this we have to process some steps in the following way:
Let us assume TableName = 'Employee' and ColumnName = 'EmployeeId'

1. Add new column 'EmployeeId_new' in the 'Employee' table
ALTER TABLE Employee ADD EmployeeId_new INT IDENTITY(1,1)

2. Now remove column 'EmployeeId' from 'Employee' table
   ALTER TABLE Employee DROP COLUMN EmployeeId

3. This will throw error because of Primary Key Constraint rules are applicable and validating column structure.
   *### 'Msg 5074, Level 16, State 1, Line 1 The object [PK_dbo.Employee] is dependent on colmn [EmployeeId].'###

4. So we have to remove the Primary Key constraint first from the table 'Employee' then we can remove the column
   ALTER TABLE Employee DROP constraint [PK_dbo.Employee]

5. Now we can remove the column 'EmployeeId' from 'Employee' table as did in the previous step where we got error
   ALTER TABLE Employee DROP COLUMN EmployeeId

6. Now Column 'EmployeeId' removed from table So we will Rename the newly added new column 'EmployeeId_new' with 'EmployeeId'
   sp_rename 'Employee.EmployeeId', 'EmployeeId_new', 'COLUMN'

7. To rearrange the table in the same form as It was, we have to add Primary Key Constraint for the column 'EmployeeId'
   ALTER TABLE Employee add constraint [PK_dbo.Employee] primary key (EmployeeId)

8. Now the table 'Employee' with 'EmployeeId' is modified for Identity rules along with existing primary key constraint

The YouTube URL in src must have and use the embed endpoint instead of watch, so for instance let’s say you want to embed this YouTube video: https://www.youtube.com/watch?v=P6N9782MzFQ (browser's URL).

You should use the embed endpoint, so the URL now should be something like https://www.youtube.com/embed/P6N9782MzFQ. Use this value as the URL in the src attribute inside the iframe tag in your HTML code, for example:

<iframe width="853" height="480" src="https://www.youtube.com/embed/P6N9782MzFQ" frameborder="0" allowfullscreen ng-show="showvideo"></iframe>

So just replace https://www.youtube.com/watch?v= with https://www.youtube.com/embed/ and of course check for your video's ID. In this sample, my video ID is P6N9782MzFQ.

You need to use jackson-module-kotlin to deserialize to data classes. See here for details.

The error message above is what Jackson gives you if you try to deserialize some value into a data class when that module isn't enabled or, even if it is, when the ObjectMapper it uses doesn't have the KotlinModule registered. For example, take this code:

data class TestDataClass (val foo: String)

val jsonString = """{ "foo": "bar" }"""
val deserializedValue = ObjectMapper().readerFor(TestDataClass::class.java).readValue<TestDataClass>(jsonString)

This will fail with the following error:

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of `test.SerializationTests$TestDataClass` (although at least one Creator exists): cannot deserialize from Object value (no delegate- or property-based Creator)

If you change the code above and replace ObjectMapper with jacksonObjectMapper (which simply returns a normal ObjectMapper with the KotlinModule registered), it works. i.e.

val deserializedValue = jacksonObjectMapper().readerFor(TestDataClass::class.java).readValue<TestDataClass>(jsonString)

I'm not sure about the Android side of things, but it looks like you'll need to get the system to use the jacksonObjectMapper to do the deserialization.

A core is usually the basic computation unit of the CPU - it can run a single program context (or multiple ones if it supports hardware threads such as hyperthreading on Intel CPUs), maintaining the correct program state, registers, and correct execution order, and performing the operations through ALUs. For optimization purposes, a core can also hold on-core caches with copies of frequently used memory chunks.

A CPU may have one or more cores to perform tasks at a given time. These tasks are usually software processes and threads that the OS schedules. Note that the OS may have many threads to run, but the CPU can only run X such tasks at a given time, where X = number cores * number of hardware threads per core. The rest would have to wait for the OS to schedule them whether by preempting currently running tasks or any other means.

In addition to the one or many cores, the CPU will include some interconnect that connects the cores to the outside world, and usually also a large "last-level" shared cache. There are multiple other key elements required to make a CPU work, but their exact locations may differ according to design. You'll need a memory controller to talk to the memory, I/O controllers (display, PCIe, USB, etc..). In the past these elements were outside the CPU, in the complementary "chipset", but most modern design have integrated them into the CPU.

In addition the CPU may have an integrated GPU, and pretty much everything else the designer wanted to keep close for performance, power and manufacturing considerations. CPU design is mostly trending in to what's called system on chip (SoC).

This is a "classic" design, used by most modern general-purpose devices (client PC, servers, and also tablet and smartphones). You can find more elaborate designs, usually in the academy, where the computations is not done in basic "core-like" units.

I'm looking at a similar problem, and I've found some of the best references come from chemistry (from peaks finding in mass-spec data). For a good thorough review of peaking finding algorithms read this. This is one of the best clearest reviews of peak finding techniques that I've run across. (Wavelets are the best for finding peaks of this sort in noisy data.).

It looks like your peaks are clearly defined and aren't hidden in the noise. That being the case I'd recommend using smooth savtizky-golay derivatives to find the peaks (If you just differentiate the data above you'll have a mess of false positives.). This is a very effective technique and is pretty easy to implemented (you do need a matrix class w/ basic operations). If you simply find the zero crossing of the first S-G derivative I think you'll be happy.

Just because this is what I got when I Googled this error, my problem was that I had

if (value < other.value)
  return -1;
else if (value >= other.value)
  return 1;
else
  return 0;

the value >= other.value should (obviously) actually be value > other.value so that you can actually return 0 with equal objects.

You can do this using the WITH clause of the SELECT statement:

;
WITH my_select As (SELECT ... FROM ...) 
SELECT * FROM foo
WHERE id IN (SELECT MAX(id) FROM my_select GROUP BY name)

That's the ANSI/ISO SQL Syntax. I know that SQL Server, Oracle and DB2 support it. Not sure about the others...

var interval = $interval(function() {
  console.log('say hello');
}, 1000);

$interval.cancel(interval);

i had a same issue because of my Nvidea Graphics card Driver Problem.

If your System has Dedicated Graphics card then Check for the latest Driver and Install it.

Other wise simply Choose Emulated Performance as Software in Emulator Configurations

After Updating the driver the issue is resolved :)

   <?xml version="1.0"?>  
<configuration>  
  <appSettings>  
    <!--FailIfMissing=false -->  
    <add key="DbSQLite" value="data source=|DataDirectory|DB.db3;Pooling=true;FailIfMissing=false"/>  
  </appSettings>  
</configuration>  

You can use the instanceof operator (but see caveat below!).

var myError = new Error('foo');
myError instanceof Error // true
var myString = "Whatever";
myString instanceof Error // false

The above won't work if the error was thrown in a different window/frame/iframe than where the check is happening. In that case, the instanceof Error check will return false, even for an Error object. In that case, the easiest approach is duck-typing.

if (myError && myError.stack && myError.message) {
  // it's an error, probably
}

However, duck-typing may produce false positives if you have non-error objects that contain stack and message properties.

The approach I took reads the header information from the first row to determine the indexes of the columns of interest.

You mentioned in the question that you also want the values output to a string. I dynamically build a format string for the output from the FORMAT column list. Rows are appended to the values string separated by a new line char.

The output column order is determined by the order of the column names in the FORMAT list.

In my code below the case of the column name in the FORMAT list is important. In the question above you've got 'Pincode' in your FORMAT list, but 'PinCode' in your excel. This wouldn't work below, it would need to be 'PinCode'.

from xlrd import open_workbook
wb = open_workbook('sample.xls')

FORMAT = ['Arm_id', 'DSPName', 'PinCode']
values = ""

for s in wb.sheets():
    headerRow = s.row(0)
    columnIndex = [x for y in FORMAT for x in range(len(headerRow)) if y == firstRow[x].value]
    formatString = ("%s,"*len(columnIndex))[0:-1] + "\n"

    for row in range(1,s.nrows):
        currentRow = s.row(row)
        currentRowValues = [currentRow[x].value for x in columnIndex]
        values += formatString % tuple(currentRowValues)

print values

For the sample input you gave above this code outputs:

>>> 1.0,JaVAS,282001.0
2.0,JaVAS,282002.0
3.0,JaVAS,282003.0

And because I'm a python noob, props be to: this answer, this answer, this question, this question and this answer.

This is explained in Apple's documentation, but below are some examples of what is actually happening.

Note that there is no "atomic" keyword, if you do not specify "nonatomic", then the property is atomic, but specifying "atomic" explicitly will result in an error.

If you do not specify "nonatomic", then the property is atomic, but you can still specify "atomic" explicitly in recent versions if you want to.

//@property(nonatomic, retain) UITextField *userName;
//Generates roughly

- (UITextField *) userName {
    return userName;
}

- (void) setUserName:(UITextField *)userName_ {
    [userName_ retain];
    [userName release];
    userName = userName_;
}

Now, the atomic variant is a bit more complicated:

//@property(retain) UITextField *userName;
//Generates roughly

- (UITextField *) userName {
    UITextField *retval = nil;
    @synchronized(self) {
        retval = [[userName retain] autorelease];
    }
    return retval;
}

- (void) setUserName:(UITextField *)userName_ {
    @synchronized(self) {
      [userName_ retain];
      [userName release];
      userName = userName_;
    }
}

Basically, the atomic version has to take a lock in order to guarantee thread safety, and also is bumping the ref count on the object (and the autorelease count to balance it) so that the object is guaranteed to exist for the caller, otherwise there is a potential race condition if another thread is setting the value, causing the ref count to drop to 0.

There are actually a large number of different variants of how these things work depending on whether the properties are scalar values or objects, and how retain, copy, readonly, nonatomic, etc interact. In general the property synthesizers just know how to do the "right thing" for all combinations.

df <- data.frame(x=rnorm(10), y=rnorm(10))
rownames(df) <-  letters[1:10]
df[c('a','b'),]

laravel 7.* You don't have to speicify JSON RESPONSE cause it's automatically converted it to JSON

return response(['Message'=>'Wrong Credintals'], 400);

For me the easiest way is to take all the values returned by image.shape:

height, width, channels = img.shape

if you don't want the number of channels (useful to determine if the image is bgr or grayscale) just drop the value:

height, width, _ = img.shape

Select * from Users where RegistrationDate >= CONVERT(datetime, '01/20/2009', 103)

is safe to use, independent of the date settings on the server.

In my case I had to put it in the bin folder of my project even the fact that my classpath is set to the src folder. I have no idea why, but it's worth a try.

The docs indicate that numpy.correlate is not what you are looking for:

numpy.correlate(a, v, mode='valid', old_behavior=False)[source]
  Cross-correlation of two 1-dimensional sequences.
  This function computes the correlation as generally defined in signal processing texts:
     z[k] = sum_n a[n] * conj(v[n+k])
  with a and v sequences being zero-padded where necessary and conj being the conjugate.

Instead, as the other comments suggested, you are looking for a Pearson correlation coefficient. To do this with scipy try:

from scipy.stats.stats import pearsonr   
a = [1,4,6]
b = [1,2,3]   
print pearsonr(a,b)

This gives

(0.99339926779878274, 0.073186395040328034)

You can also use numpy.corrcoef:

import numpy
print numpy.corrcoef(a,b)

This gives:

[[ 1.          0.99339927]
 [ 0.99339927  1.        ]]

JS

        function showAlert(){
         $('#alert').show();
         setTimeout(function() { 
             $('#alert').hide(); 
         }, 5000);
        }

HTML

<div class="alert alert-success" id="alert" role="alert" style="display:none;" >YOUR MESSAGE</div>

I had same symptoms.

Please ensure you have the proper Visual Studio extension installed via Tools - Extensions and Updates. In my case, I had to install XUnit and Specflow from the Online option.

Then clean the solution and rebuild it.

If that still doesn't help, clear your temp directory (search for %temp% in the Start menu search and delete all contents in Temp)

And then finally try uninstalling Resharper which finally fixed my problem.

I encountered this problem when I accidentally tried running my python module through the command prompt while my working directory was C:\Windows\System32 instead of the usual directory from which I run my python module

This could be done simpler:

<base href="${pageContext.request.contextPath}/"/>

All URL will be formed without unnecessary domain:port but with application context.

I do that as

    $slightly_damaged = array_merge(
        array_slice($slightly_damaged, 0, 4, true) + ["4" => "0.0"], 
        array_slice($slightly_damaged, 4, count($slightly_damaged) - 4, true)
    );

I like Microsoft's XML Notepad 2007, but I don't know how it handles very large files, sorry.

Not sure what you are asking, but... Class.forname, maybe?

Late to the party, but a clean way to do this on a per-project basis, is to add a .editorconfig file to the root of the project. Saves you from having to change Atom's settings when you're working on several projects simultaneously.

This is a sample of a very basic setup I'm currently using. Works for Atom, ST, etc...

http://editorconfig.org/

# Automatically add new line to end of all files on save.
[*]
insert_final_newline = true

# 2 space indentation for SASS/CSS
[*.{scss,sass,css}]
indent_style = space
indent_size = 2

# Set all JS to tab => space*2
[js/**.js]
indent_style = space
indent_size = 2

Python 3 has the facility of launching parallel tasks. This makes our work easier.

It has thread pooling and process pooling.

The following gives an insight:

ThreadPoolExecutor Example (source)

# Retrieve a single page and report the URL and contents
def load_url(url, timeout):
    with urllib.request.urlopen(url, timeout=timeout) as conn:

Another way to control it via Profiles is this:

// note: no @SpringApplication annotation here
@Import(DatabaseConfig.class)
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

@Import({DatabaseConfig.WithDB.class, DatabaseConfig.WithoutDB.class})
public class DatabaseConfig {

    @Profile("!db")
    @EnableAutoConfiguration(
            exclude = {DataSourceAutoConfiguration.class,   DataSourceTransactionManagerAutoConfiguration.class,
                HibernateJpaAutoConfiguration.class})
    static class WithoutDB {

    }

    @Profile("db")
    @EnableAutoConfiguration
    static class WithDB {

    }
}

You can't change PHP version by .htaccess.

you need to get your server updated, for PHP 5.3 or you can find another host, which serves PHP 5.3 on shared hosting.

Export your table, then empty your table, then add field as unique INT, then change it to AUTO_INCREMENT, then import your table again that you exported previously.

With VSCode 1.47+ you can simply use OPT-w for this.

Utilizing built-in functionality to trigger emmet, this is the easiest way:

1. Select your text/html.
2. Option+w
3. In the emmet window opened in the command palette, type in the tag or wrapping code you need.
4. Enter
5. Voila

I really miss that feature. Only way to achieve something similar is to use functions.

I have used it in two ways:

• perl functions that use $_SHARED variable
• store your variables in table

Perl version:

   CREATE FUNCTION var(name text, val text) RETURNS void AS $$
        $_SHARED{$_[0]} = $_[1];
   $$ LANGUAGE plperl;
   CREATE FUNCTION var(name text) RETURNS text AS $$
        return $_SHARED{$_[0]};
   $$ LANGUAGE plperl;

Table version:

CREATE TABLE var (
  sess bigint NOT NULL,
  key varchar NOT NULL,
  val varchar,
  CONSTRAINT var_pkey PRIMARY KEY (sess, key)
);
CREATE FUNCTION var(key varchar, val anyelement) RETURNS void AS $$
  DELETE FROM var WHERE sess = pg_backend_pid() AND key = $1;
  INSERT INTO var (sess, key, val) VALUES (sessid(), $1, $2::varchar);
$$ LANGUAGE 'sql';

CREATE FUNCTION var(varname varchar) RETURNS varchar AS $$
  SELECT val FROM var WHERE sess = pg_backend_pid() AND key = $1;
$$ LANGUAGE 'sql';

Notes:

• plperlu is faster than perl
• pg_backend_pid is not best session identification, consider using pid combined with backend_start from pg_stat_activity
• this table version is also bad because you have to clear this is up occasionally (and not delete currently working session variables)

To delete an object by it's id in given array;

const hero = [{'id' : 1, 'name' : 'hero1'}, {'id': 2, 'name' : 'hero2'}];
//remove hero1
const updatedHero = hero.filter(item => item.id !== 1);

My case was that I had generated code for three custom content types and then just pasted all the code in functions.php without renaming the "function custom_post_type" part of each function. After renaming like e.g "function employees", it worked like a charm....it displayed.

Try this

tar -pczvf advancedarts.tar.gz /home/user/public_html/ --exclude /home/user/public_html/tmp

To disable the hover effect, I've got two suggestions:

• if your hover effect is triggered by JavaScript, just use $.unbind('hover');
• if your hover style is triggered by class, then just use $.removeClass('hoverCssClass');

Using CSS !important to override CSS will make your CSS very unclean thus that method is not recommended. You can always duplicate a CSS style with different class name to keep the same styling.

Per the comment of Larson, this is now possible with the save-actions plugin.

 just change it to 

compile 'com.google.android.gms:play-services-maps:9.6.0'
compile 'com.google.android.gms:play-services-location:9.6.0'

this works for me current version is 10.0.1

A better idea,

if you want to put the error message just beneath the text field, you can do like this

.row.spacer20top
  .col-sm-6.form-group
    = f.label :first_name, "*Your First Name:"
    = f.text_field :first_name, :required => true, class: "form-control"
    = f.error_message_for(:first_name)

What is error_message_for?
--> Well, this is a beautiful hack to do some cool stuff

Don't run it though addslashes(); if you're in the context of the HTML page, the HTML parser can still see the </script> tag, even mid-string, and assume it's the end of the JavaScript:

<?php
    $value = 'XXX</script><script>alert(document.cookie);</script>';
?>

<script type="text/javascript">
    var foo = <?= json_encode($value) ?>; // Use this
    var foo = '<?= addslashes($value) ?>'; // Avoid, allows XSS!
</script>

Thanks for the answer of https://stackoverflow.com/a/65513726/889126, it gave me an idea to make a complete bash script as it is

export api_image_id=$(docker inspect --format="{{.Id}}" <image-name> | sed '/^[[:space:]]*$/d')

sudo docker exec -i -t ${api_image_id} /bin/bash

I need a specific container and make a script to extract some info from it in a quick sight.

Hope this would help others.

Please note , you might need to disable adblocks if necessary. Drag and drop off script path in visual studio doesn't work if you are using HTML pages but it does work for mvc ,asp.netwebforms. I figured this after one hour

Personally, I like to use named entities when they are available, because they make my HTML more readable. Because of that, I like to use ✓ for ✓ and ✗ for ✗. If you're not sure whether a named entity exists for the character you want, try the &what search site. It includes the name for each entity, if there is one.

As mentioned in the comments, ✓ and ✗ are not supported in HTML4, so you may be better off using the more cryptic ✓ and ✗ if you want to target the most browsers. The most definitive references I could find were on the W3C site: HTML4 and HTML5.

Note many third-party clients have own timezone settings overlapping any Postgres server and\or session settings.

E.g. if you're using 'IntelliJ IDEA 2017.3' (or DataGrips), you should define timezone as:

'DB source properties' -> 'Advanced' tab -> 'VM Options': -Duser.timezone=UTC+06:00

otherwise you will see 'UTC' despite of whatever you have set anywhere else.

This happens every time you insert/ update and you don't use single quotes. When the variable is empty it will result in that error. Fix it by using ''

Assuming the first parameter is an empty variable here is a simple example:

Wrong

nvl( ,0)

Fix

nvl('' ,0)

Put your query into your database software and check it for that error. Generally this is an easy fix

I think you want to specify

-H "Content-Type:text/xml"

with a colon, not an equals.

Pure Java:

 urlToInputStream(url,httpHeaders);

With some success I use this method. It handles redirects and one can pass a variable number of HTTP headers asMap<String,String>. It also allows redirects from HTTP to HTTPS.

private InputStream urlToInputStream(URL url, Map<String, String> args) {
    HttpURLConnection con = null;
    InputStream inputStream = null;
    try {
        con = (HttpURLConnection) url.openConnection();
        con.setConnectTimeout(15000);
        con.setReadTimeout(15000);
        if (args != null) {
            for (Entry<String, String> e : args.entrySet()) {
                con.setRequestProperty(e.getKey(), e.getValue());
            }
        }
        con.connect();
        int responseCode = con.getResponseCode();
        /* By default the connection will follow redirects. The following
         * block is only entered if the implementation of HttpURLConnection
         * does not perform the redirect. The exact behavior depends to 
         * the actual implementation (e.g. sun.net).
         * !!! Attention: This block allows the connection to 
         * switch protocols (e.g. HTTP to HTTPS), which is <b>not</b> 
         * default behavior. See: https://stackoverflow.com/questions/1884230 
         * for more info!!!
         */
        if (responseCode < 400 && responseCode > 299) {
            String redirectUrl = con.getHeaderField("Location");
            try {
                URL newUrl = new URL(redirectUrl);
                return urlToInputStream(newUrl, args);
            } catch (MalformedURLException e) {
                URL newUrl = new URL(url.getProtocol() + "://" + url.getHost() + redirectUrl);
                return urlToInputStream(newUrl, args);
            }
        }
        /*!!!!!*/

        inputStream = con.getInputStream();
        return inputStream;
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}

Full example call

private InputStream getInputStreamFromUrl(URL url, String user, String passwd) throws IOException {
        String encoded = Base64.getEncoder().encodeToString((user + ":" + passwd).getBytes(StandardCharsets.UTF_8));
        Map<String,String> httpHeaders=new Map<>();
        httpHeaders.put("Accept", "application/json");
        httpHeaders.put("User-Agent", "myApplication");
        httpHeaders.put("Authorization", "Basic " + encoded);
        return urlToInputStream(url,httpHeaders);
    }

Even if you capture the keydown/keyup event, those are the only events that the tab key fires, you still need some way to prevent the default action, moving to the next item in the tab order, from occurring.

In Firefox you can call the preventDefault() method on the event object passed to your event handler. In IE, you have to return false from the event handle. The JQuery library provides a preventDefault method on its event object that works in IE and FF.

<body>
<input type="text" id="myInput">
<script type="text/javascript">
    var myInput = document.getElementById("myInput");
    if(myInput.addEventListener ) {
        myInput.addEventListener('keydown',this.keyHandler,false);
    } else if(myInput.attachEvent ) {
        myInput.attachEvent('onkeydown',this.keyHandler); /* damn IE hack */
    }

    function keyHandler(e) {
        var TABKEY = 9;
        if(e.keyCode == TABKEY) {
            this.value += "    ";
            if(e.preventDefault) {
                e.preventDefault();
            }
            return false;
        }
    }
</script>
</body>

You can try following code:

foreach ($arry as $key => $value) 
{
      echo $key;
      foreach ($value as  $val) 
      {
         echo $val; 
      }
}

You were close

You need to Use with a Using statement to contain some code to run impersonated.

List(1,2,3) :+ 4

Results in List[Int] = List(1, 2, 3, 4)

Note that this operation has a complexity of O(n). If you need this operation frequently, or for long lists, consider using another data type (e.g. a ListBuffer).

I just wanna add this, when you access the position of the array like

arg[n]

is the same as

*(arg + n) than means an offset of n starting from de arg address.

so arg[0] will be *arg

As indicated in the question, every sub-command is run in its own shell. This makes writing non-trivial shell scripts a little bit messy -- but it is possible! The solution is to consolidate your script into what make will consider a single sub-command (a single line).

Tips for writing shell scripts within makefiles:

1. Escape the script's use of $ by replacing with $$
2. Convert the script to work as a single line by inserting ; between commands
3. If you want to write the script on multiple lines, escape end-of-line with \
4. Optionally start with set -e to match make's provision to abort on sub-command failure
5. This is totally optional, but you could bracket the script with () or {} to emphasize the cohesiveness of a multiple line sequence -- that this is not a typical makefile command sequence

Here's an example inspired by the OP:

mytarget:
    { \
    set -e ;\
    msg="header:" ;\
    for i in $$(seq 1 3) ; do msg="$$msg pre_$${i}_post" ; done ;\
    msg="$$msg :footer" ;\
    echo msg=$$msg ;\
    }

This is something I've also been struggling with for my own images. I have a server environment from which I create a Docker image. When I update the server, I'd like all users who are running containers based on my Docker image to be able to upgrade to the latest server.

Ideally, I'd prefer to generate a new version of the Docker image and have all containers based on a previous version of that image automagically update to the new image "in place." But this mechanism doesn't seem to exist.

So the next best design I've been able to come up with so far is to provide a way to have the container update itself--similar to how a desktop application checks for updates and then upgrades itself. In my case, this will probably mean crafting a script that involves Git pulls from a well-known tag.

The image/container doesn't actually change, but the "internals" of that container change. You could imagine doing the same with apt-get, yum, or whatever is appropriate for you environment. Along with this, I'd update the myserver:latest image in the registry so any new containers would be based on the latest image.

I'd be interested in hearing whether there is any prior art that addresses this scenario.

This is a confusion between constructors and instances.

Remember that when you write a component in React:

class Greeter extends React.Component<any, any> {
    render() {
        return <div>Hello, {this.props.whoToGreet}</div>;
    }
}

You use it this way:

return <Greeter whoToGreet='world' />;

You don't use it this way:

let Greet = new Greeter();
return <Greet whoToGreet='world' />;

In the first example, we're passing around Greeter, the constructor function for our component. That's the correct usage. In the second example, we're passing around an instance of Greeter. That's incorrect, and will fail at runtime with an error like "Object is not a function".

The problem with this code

function renderGreeting(Elem: React.Component<any, any>) {
    return <span>Hello, <Elem />!</span>;
}

is that it's expecting an instance of React.Component. What you want is a function that takes a constructor for React.Component:

function renderGreeting(Elem: new() => React.Component<any, any>) {
    return <span>Hello, <Elem />!</span>;
}

or similarly:

function renderGreeting(Elem: typeof React.Component) {
    return <span>Hello, <Elem />!</span>;
}

This is improvement of Prateek answer - event is pass by parameter so reply_click not need to use global variable (and as far no body presents this variant)

function reply_click(e) {
  console.log(e.target.id);
}

<button id="1" onClick="reply_click(event)">B1</button>
<button id="2" onClick="reply_click(event)">B2</button>
<button id="3" onClick="reply_click(event)">B3</button>

Diffrence between Foreach & map :

Map() : If you use map then map can return new array by iterating main array.

Foreach() : If you use Foreach then it can not return anything for each can iterating main array.

Chris Fulstow's solution will work (+1), however, it may not be efficient, especially if your collection is very large. Non-rooted regular expressions (those not beginning with ^, which anchors the regular expression to the start of the string), and those using the i flag for case insensitivity will not use indexes, even if they exist.

An alternative option you might consider is to denormalize your data to store a lower-case version of the name field, for instance as name_lower. You can then query that efficiently (especially if it is indexed) for case-insensitive exact matches like:

db.collection.find({"name_lower": thename.toLowerCase()})

Or with a prefix match (a rooted regular expression) as:

db.collection.find( {"name_lower":
    { $regex: new RegExp("^" + thename.toLowerCase(), "i") } }
);

Both of these queries will use an index on name_lower.

this is what worked for me :

1 -->  ng g module new-module

2 -->  ng g c new-module/component-test --module=new-module/new-module.module.ts

If you want to generate a component without its directory use --flat flag.

The accepted answer by Francisco Spaeth works and is easy to follow. However, I think that method of building JSON sucks! This was really driven home for me as I converted some Python to Java where I could use dictionaries and nested lists, etc. to build JSON with ridiculously greater ease.

What I really don't like is having to instantiate separate objects (and generally even name them) to build up these nestings. If you have a lot of objects or data to deal with, or your use is more abstract, that is a real pain!

I tried getting around some of that by attempting to clear and reuse temp json objects and lists, but that didn't work for me because all the puts and gets, etc. in these Java objects work by reference not value. So, I'd end up with JSON objects containing a bunch of screwy data after still having some ugly (albeit differently styled) code.

So, here's what I came up with to clean this up. It could use further development, but this should help serve as a base for those of you looking for more reasonable JSON building code:

import java.util.AbstractMap.SimpleEntry;
import java.util.ArrayList;
import java.util.List;
import org.json.simple.JSONObject;

//  create and initialize an object 
public static JSONObject buildObject( final SimpleEntry... entries ) { 
    JSONObject object = new JSONObject();
    for( SimpleEntry e : entries ) object.put( e.getKey(), e.getValue() );
    return object;
}

//  nest a list of objects inside another                          
public static void putObjects( final JSONObject parentObject, final String key,
                               final JSONObject... objects ) { 
    List objectList = new ArrayList<JSONObject>();
    for( JSONObject o : objects ) objectList.add( o );
    parentObject.put( key, objectList );
}   

Implementation example:

JSONObject jsonRequest = new JSONObject();
putObjects( jsonRequest, "parent1Key",
    buildObject( 
        new SimpleEntry( "child1Key1", "someValue" )
      , new SimpleEntry( "child1Key2", "someValue" ) 
    )
  , buildObject( 
        new SimpleEntry( "child2Key1", "someValue" )
      , new SimpleEntry( "child2Key2", "someValue" ) 
    )
);      

It's an optimization of your algorithm that cuts running time.

While a Greedy Algorithm is usually called naive, because it may run multiple times over the same set of data, Dynamic Programming avoids this pitfall through a deeper understanding of the partial results that must be stored to help build the final solution.

A simple example is traversing a tree or a graph only through the nodes that would contribute with the solution, or putting into a table the solutions that you've found so far so you can avoid traversing the same nodes over and over.

Here's an example of a problem that's suited for dynamic programming, from UVA's online judge: Edit Steps Ladder.

I'm going to make quick briefing of the important part of this problem's analysis, taken from the book Programming Challenges, I suggest you check it out.

Take a good look at that problem, if we define a cost function telling us how far appart two strings are, we have two consider the three natural types of changes:

Substitution - change a single character from pattern "s" to a different character in text "t", such as changing "shot" to "spot".

Insertion - insert a single character into pattern "s" to help it match text "t", such as changing "ago" to "agog".

Deletion - delete a single character from pattern "s" to help it match text "t", such as changing "hour" to "our".

When we set each of this operations to cost one step we define the edit distance between two strings. So how do we compute it?

We can define a recursive algorithm using the observation that the last character in the string must be either matched, substituted, inserted or deleted. Chopping off the characters in the last edit operation leaves a pair operation leaves a pair of smaller strings. Let i and j be the last character of the relevant prefix of and t, respectively. there are three pairs of shorter strings after the last operation, corresponding to the string after a match/substitution, insertion or deletion. If we knew the cost of editing the three pairs of smaller strings, we could decide which option leads to the best solution and choose that option accordingly. We can learn this cost, through the awesome thing that's recursion:

#define MATCH 0 /* enumerated type symbol for match */
#define INSERT 1 /* enumerated type symbol for insert */
#define DELETE 2 /* enumerated type symbol for delete */


int string_compare(char *s, char *t, int i, int j)

{

    int k; /* counter */
    int opt[3]; /* cost of the three options */
    int lowest_cost; /* lowest cost */
    if (i == 0) return(j * indel(’ ’));
    if (j == 0) return(i * indel(’ ’));
    opt[MATCH] = string_compare(s,t,i-1,j-1) +
      match(s[i],t[j]);
    opt[INSERT] = string_compare(s,t,i,j-1) +
      indel(t[j]);
    opt[DELETE] = string_compare(s,t,i-1,j) +
      indel(s[i]);
    lowest_cost = opt[MATCH];
    for (k=INSERT; k<=DELETE; k++)
    if (opt[k] < lowest_cost) lowest_cost = opt[k];
    return( lowest_cost );

}

This algorithm is correct, but is also impossibly slow.

Running on our computer, it takes several seconds to compare two 11-character strings, and the computation disappears into never-never land on anything longer.

Why is the algorithm so slow? It takes exponential time because it recomputes values again and again and again. At every position in the string, the recursion branches three ways, meaning it grows at a rate of at least 3^n – indeed, even faster since most of the calls reduce only one of the two indices, not both of them.

So how can we make the algorithm practical? The important observation is that most of these recursive calls are computing things that have already been computed before. How do we know? Well, there can only be |s| · |t| possible unique recursive calls, since there are only that many distinct (i, j) pairs to serve as the parameters of recursive calls.

By storing the values for each of these (i, j) pairs in a table, we can avoid recomputing them and just look them up as needed.

The table is a two-dimensional matrix m where each of the |s|·|t| cells contains the cost of the optimal solution of this subproblem, as well as a parent pointer explaining how we got to this location:

typedef struct {
int cost; /* cost of reaching this cell */
int parent; /* parent cell */
} cell;

cell m[MAXLEN+1][MAXLEN+1]; /* dynamic programming table */

The dynamic programming version has three differences from the recursive version.

First, it gets its intermediate values using table lookup instead of recursive calls.

**Second,**it updates the parent field of each cell, which will enable us to reconstruct the edit sequence later.

**Third,**Third, it is instrumented using a more general goal cell() function instead of just returning m[|s|][|t|].cost. This will enable us to apply this routine to a wider class of problems.

Here, a very particular analysis of what it takes to gather the most optimal partial results, is what makes the solution a "dynamic" one.

Here's an alternate, full solution to the same problem. It's also a "dynamic" one even though its execution is different. I suggest you check out how efficient the solution is by submitting it to UVA's online judge. I find amazing how such a heavy problem was tackled so efficiently.

If the device is rooted,

Seems to do the trick.

How do pointers to pointers work in C?

First a pointer is a variable, like any other variable, but that holds the address of a variable.

A pointer to a pointer is a variable, like any other variable, but that holds the address of a variable. That variable just happens to be a pointer.

When would you use them?

You can use them when you need to return a pointer to some memory on the heap, but not using the return value.

Example:

int getValueOf5(int *p)
{
  *p = 5;
  return 1;//success
}

int get1024HeapMemory(int **p)
{
  *p = malloc(1024);
  if(*p == 0)
    return -1;//error
  else 
    return 0;//success
}

And you call it like this:

int x;
getValueOf5(&x);//I want to fill the int varaible, so I pass it's address in
//At this point x holds 5

int *p;    
get1024HeapMemory(&p);//I want to fill the int* variable, so I pass it's address in
//At this point p holds a memory address where 1024 bytes of memory is allocated on the heap

There are other uses too, like the main() argument of every C program has a pointer to a pointer for argv, where each element holds an array of chars that are the command line options. You must be careful though when you use pointers of pointers to point to 2 dimensional arrays, it's better to use a pointer to a 2 dimensional array instead.

Why it's dangerous?

void test()
{
  double **a;
  int i1 = sizeof(a[0]);//i1 == 4 == sizeof(double*)

  double matrix[ROWS][COLUMNS];
  int i2 = sizeof(matrix[0]);//i2 == 240 == COLUMNS * sizeof(double)
}

Here is an example of a pointer to a 2 dimensional array done properly:

int (*myPointerTo2DimArray)[ROWS][COLUMNS]

You can't use a pointer to a 2 dimensional array though if you want to support a variable number of elements for the ROWS and COLUMNS. But when you know before hand you would use a 2 dimensional array.

No, there isn't an equivalent. The <iframe> element is still valid in HTML5. Depending on what exact interaction you need there might be different APIs. For example there's the postMessage method which allows you to achieve cross domain javascript interaction. But if you want to display cross domain HTML contents (styled with CSS and made interactive with javascript) iframe stays as a good way to do.

Contrary to what is commonly believed, named parameters can be implemented in standard, old-school JavaScript (for boolean parameters only) by means of a simple, neat coding convention, as shown below.

function f(p1=true, p2=false) {
    ...
}

f(!!"p1"==false, !!"p2"==true); // call f(p1=false, p2=true)

Caveats:

• Ordering of arguments must be preserved - but the pattern is still useful, since it makes it obvious which actual argument is meant for which formal parameter without having to grep for the function signature or use an IDE.

• This only works for booleans. However, I'm sure a similar pattern could be developed for other types using JavaScript's unique type coercion semantics.

You can use a sealed abstract class instead of the enumeration, for example:

sealed abstract class Constraint(val name: String, val verifier: Int => Boolean)

case object NotTooBig extends Constraint("NotTooBig", (_ < 1000))
case object NonZero extends Constraint("NonZero", (_ != 0))
case class NotEquals(x: Int) extends Constraint("NotEquals " + x, (_ != x))

object Main {

  def eval(ctrs: Seq[Constraint])(x: Int): Boolean =
    (true /: ctrs){ case (accum, ctr) => accum && ctr.verifier(x) }

  def main(args: Array[String]) {
    val ctrs = NotTooBig :: NotEquals(5) :: Nil
    val evaluate = eval(ctrs) _

    println(evaluate(3000))
    println(evaluate(3))
    println(evaluate(5))
  }

}

I did something like this in my project. I would like to share it here. You can add another div as a child and give it a border with small width and place it left, centre or right with usual CSS

HTML code:

    <div>
        content 
        <div class ="ac-brdr"></div>
    </div>

CSS as below:

   .active {
    color: magneta;
  }
   .active .ac-brdr {
        width: 20px;
        margin: 0 auto;
        border-bottom: 1px solid magneta;
  }

TMTOWTDI, chose the method that best fits how you work. I use the environment method so I don't have to think about it.

In the environment:

export PERL_UNICODE=SDL

on the command line:

perl -CSDL -le 'print "\x{1815}"';

or with binmode:

binmode(STDOUT, ":utf8");          #treat as if it is UTF-8
binmode(STDIN, ":encoding(utf8)"); #actually check if it is UTF-8

or with PerlIO:

open my $fh, ">:utf8", $filename
    or die "could not open $filename: $!\n";

open my $fh, "<:encoding(utf-8)", $filename
    or die "could not open $filename: $!\n";

or with the open pragma:

use open ":encoding(utf8)";
use open IN => ":encoding(utf8)", OUT => ":utf8";

Prior to PHP 5.5, the the PHP docs used to say:

empty() only checks variables as anything else will result in a parse error

In PHP < 5.5 you weren't able use empty() directly on a function's return value. Instead, you could assign the return from getError() to a variable and run empty() on the variable.

In PHP >= 5.5 this is no longer necessary.

in my case i already had the maven dependency to 'spring-boot-starter-web' and the project would start fine without auto-stopping when i run it as springboot app from within the IDE. however, when i deploy it to K8s, the app would start and auto-stop immediately. So i modified my main app class to extend SpringBootServletInitializer and this seems to have fixed the auto-stopping.

@SpringBootApplication public class MyApp extends SpringBootServletInitializer {  public static void main(String[] args) {
SpringApplication.run(MyApp.class, args);  }}

I have found that the 65536 limit still applies to pivot tables, even in Excel 2007.

The idea is to use innerHTML on an intermediary element and then move all of its child nodes to where you really want them via appendChild.

var target = document.getElementById('test');
var str = '<p>Just some <span>text</span> here</p>';

var temp = document.createElement('div');
temp.innerHTML = str;
while (temp.firstChild) {
  target.appendChild(temp.firstChild);
}

This avoids wiping out any event handlers on div#test but still allows you to append a string of HTML.

Your regex does not work because [] defines a character class, but what you want is a lookahead:

(?=) - Positive look ahead assertion foo(?=bar) matches foo when followed by bar
(?!) - Negative look ahead assertion foo(?!bar) matches foo when not followed by bar
(?<=) - Positive look behind assertion (?<=foo)bar matches bar when preceded by foo
(?<!) - Negative look behind assertion (?<!foo)bar matches bar when NOT preceded by foo
(?>) - Once-only subpatterns (?>\d+)bar Performance enhancing when bar not present
(?(x)) - Conditional subpatterns
(?(3)foo|fu)bar - Matches foo if 3rd subpattern has matched, fu if not
(?#) - Comment (?# Pattern does x y or z)

So try: (?!bush)

class Feedback(models.Model):
   feedback = models.CharField(max_length=100)
   created = models.DateTimeField(auto_now_add=True)
   updated = models.DateTimeField(auto_now=True)

Here, we have created and updated columns that will have a timestamp when created, and when someone modified feedback.

auto_now_add will set time when an instance is created whereas auto_now will set time when someone modified his feedback.

The compiler cannot tell from that code if the function will ever reach the end and still return something. To make that clear, replace the last else if(...) with just else.

Once Windows learns a program uses higher than normal priority it seems like it limits the priority on the process.

Setting the priority from IDLE to REALTIME does NOT change the CPU usage.

I found on My multi-processor AMD CPU that if I drop one of the CPUs ot like the LAST one the CPU usage will MAX OUT and the last CPU remains idle. The processor speed increases to 75% on my Quad AMD.

Use Task Manager->select process->Right Click on the process->Select->Set Affinity Click all but the last processor. The CPU usage will increase to the MAX on the remaining processors and Frame counts if processing video will increase.

In simple word "you can't do it through simple setListAdapter" . you must used custom listview for freely changes in text color or in any other views

for Custom Listview you can go with this link

Here is the code I was looking for :

DDL.SelectedIndex = DDL.Items.IndexOf(DDL.Items.FindByText("PassedValue"));

Or

DDL.SelectedIndex = DDL.Items.IndexOf(DDL.Items.FindByValue("PassedValue"));

EDIT:

Ok I found why the int.ToString() in LINQtoEF fails, please read this post: Problem with converting int to string in Linq to entities

This works on my side :

        List<string> materialTypes = (from u in result.Users
                                      select u.LastName)
                       .Union(from u in result.Users
                               select SqlFunctions.StringConvert((double) u.UserId)).ToList();

On yours it should be like this:

    IList<String> materialTypes = ((from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select tom.Name)
                                       .Union(from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select SqlFunctions.StringConvert((double)tom.ID))).ToList();

Thanks, i've learnt something today :)

after your pc connects to other pc use these 4 step:
4 steps:
1- Edit this file: httpd.conf
for that click on wamp server and select Apache and select httpd.conf
2- Find this text: Deny from all
in the below tag:

  <Directory "c:/wamp/www"><!-- maybe other url-->

     Order Deny,Allow
    Deny from all
     Allow from 127.0.0.1
     Allow from ::1
     Allow from localhost

     Allow from localhost

4- Restart Apache
Don't forget restart Apache or all servises!!!

I think that this solution is not the best, since it works only for int, but i think it's great for a beginner.

public class NumberWordConverter {
    public static final String[] units = {

            "fifteen", "sixteen", "seventeen", "eighteen", "nineteen"
    };

    public static final String[] tens = {
            "",        // 0

    };

    public static String convert(final int n) {
        if (n < 0) {
            return "minus " + convert(-n);
        }

        if (n < 20) {
            return units[n];
        }

        if (n < 100) {
            return tens[n / 10] + ((n % 10 != 0) ? " " : "") + units[n % 10];
        }

        if (n < 1000) {
            return units[n / 100] + " hundred" + ((n % 100 != 0) ? " " : "") + convert(n % 100);
        }

        if (n < 1000000) {
            return convert(n / 1000) + " thousand" + ((n % 1000 != 0) ? " " : "") + convert(n % 1000);
        }

        if (n < 1000000000) {
            return convert(n / 1000000) + " million" + ((n % 1000000 != 0) ? " " : "") + convert(n % 1000000);
        }

        return convert(n / 1000000000) + " billion"  + ((n % 1000000000 != 0) ? " " : "") + convert(n % 1000000000);
    }

    public static void main(final String[] args) {
        final Random generator = new Random();

        int n;
        for (int i = 0; i < 20; i++) {
            n = generator.nextInt(Integer.MAX_VALUE);

            System.out.printf("%10d = '%s'%n", n, convert(n));
        }

        n = 1000;
        System.out.printf("%10d = '%s'%n", n, convert(n));

        n = 2000;
        System.out.printf("%10d = '%s'%n", n, convert(n));

        n = 10000;
        System.out.printf("%10d = '%s'%n", n, convert(n));

        n = 11000;
        System.out.printf("%10d = '%s'%n", n, convert(n));

        n = 999999999;
        System.out.printf("%10d = '%s'%n", n, convert(n));

        n = Integer.MAX_VALUE;
        System.out.printf("%10d = '%s'%n", n, convert(n));
    }
}

The test creates 20 random numbers up to Integer.MAX_VALUE and than some that know to be problematic, because of 0, 10, etc.. Output:

Hope it helps :)

You can use itertools.tee and zip to efficiently build the result:

from itertools import tee
# python2 only:
#from itertools import izip as zip

def differences(seq):
    iterable, copied = tee(seq)
    next(copied)
    for x, y in zip(iterable, copied):
        yield y - x

Or using itertools.islice instead:

from itertools import islice

def differences(seq):
    nexts = islice(seq, 1, None)
    for x, y in zip(seq, nexts):
        yield y - x

You can also avoid using the itertools module:

def differences(seq):
    iterable = iter(seq)
    prev = next(iterable)
    for element in iterable:
        yield element - prev
        prev = element

All these solution work in constant space if you don't need to store all the results and support infinite iterables.

Here are some micro-benchmarks of the solutions:

In [12]: L = range(10**6)

In [13]: from collections import deque
In [15]: %timeit deque(differences_tee(L), maxlen=0)
10 loops, best of 3: 122 ms per loop

In [16]: %timeit deque(differences_islice(L), maxlen=0)
10 loops, best of 3: 127 ms per loop

In [17]: %timeit deque(differences_no_it(L), maxlen=0)
10 loops, best of 3: 89.9 ms per loop

And the other proposed solutions:

In [18]: %timeit [x[1] - x[0] for x in zip(L[1:], L)]
10 loops, best of 3: 163 ms per loop

In [19]: %timeit [L[i+1]-L[i] for i in range(len(L)-1)]
1 loops, best of 3: 395 ms per loop

In [20]: import numpy as np

In [21]: %timeit np.diff(L)
1 loops, best of 3: 479 ms per loop

In [35]: %%timeit
    ...: res = []
    ...: for i in range(len(L) - 1):
    ...:     res.append(L[i+1] - L[i])
    ...: 
1 loops, best of 3: 234 ms per loop

Note that:

• zip(L[1:], L) is equivalent to zip(L[1:], L[:-1]) since zip already terminates on the shortest input, however it avoids a whole copy of L.
• Accessing the single elements by index is very slow because every index access is a method call in python

• numpy.diff is slow because it has to first convert the list to a ndarray. Obviously if you start with an ndarray it will be much faster:

There isn’t a pure JavaScript generic solution, I’m afraid. JavaScript isn’t able to turn off the CSS :hover state itself.

You could try the following alternative workaround though. If you don’t mind mucking about in your HTML and CSS a little bit, it saves you having to reset every CSS property manually via JavaScript.

HTML

<body class="nojQuery">

CSS

/* Limit the hover styles in your CSS so that they only apply when the nojQuery 
class is present */

body.nojQuery ul#mainFilter a:hover {
    /* CSS-only hover styles go here */
}

JavaScript

// When jQuery kicks in, remove the nojQuery class from the <body> element, thus
// making the CSS hover styles disappear.

$(function(){}
    $('body').removeClass('nojQuery');
)

I also see that the page loading (performance) takes a long time on using h:commandLink than h:link. h:link is faster compared to h:commandLink

You don't need to. Just slap it on there as many times as you want and as often as you want. MDN explains identical event listeners:

If multiple identical EventListeners are registered on the same EventTarget with the same parameters, the duplicate instances are discarded. They do not cause the EventListener to be called twice, and they do not need to be removed manually with the removeEventListener method.

Here's an example that includes initialising the show/hide to match the state of the checkbox when the page loads; taking account of the fact that firefox remembers the state of checkboxes when you refresh the page, but won't remember the state of the shown/hidden elements.

$(function() {
    // initialise visibility when page is loaded
    $('tr.invoiceItemRow').toggle($('#showInvoiceItems').attr('checked'));
    // attach click handler to checkbox
    $('#showInvoiceItems').click(function(){ $('tr.invoiceItemRow').toggle(this.checked);})
});

I am using intellij CE to create the WAR, and deploying the war externally using tomcat deployment manager. This works for testing the application however I still couldnt find the way to debug it.

1. open cmd and current dir to tomcat/bin.
2. you can start and stop the server using the batch files start.bat and shutdown.bat.
3. Now build your app using mvn goal in intellij.
4. Open localhost:8080/ **Your port number may differ.
5. Use this tomcat application to deploy the application, If you get the authentication error, you would need to set the credentials under conf/tomcat-users.xml.

Focusing on an easy syntax for describing a make target, and having a clean output, I chose this approach:

help:
    @grep -B1 -E "^[a-zA-Z0-9_-]+\:([^\=]|$$)" Makefile \
     | grep -v -- -- \
     | sed 'N;s/\n/###/' \
     | sed -n 's/^#: \(.*\)###\(.*\):.*/\2###\1/p' \
     | column -t  -s '###'


#: Starts the container stack
up: a b
  command

#: Pulls in new container images
pull: c d 
    another command

make-target-not-shown:

# this does not count as a description, so leaving
# your implementation comments alone, e.g TODOs
also-not-shown:

So treating the above as a Makefile and running it gives you something like

> make help
up          Starts the container stack
pull        Pulls in new container images

Explanation for the chain of commands:

• First, grep all targets and their preceeding line, see https://unix.stackexchange.com/a/320709/223029.
• Then, get rid of the group separator, see https://stackoverflow.com/a/2168139/1242922.
• Then, we collapse each pair of lines to parse it later, see https://stackoverflow.com/a/9605559/1242922.
• Then, we parse for valid lines and remove those which do not match, see https://stackoverflow.com/a/8255627/1242922, and also give the output our desired order: command, then description.
• Lastly, we arrange the output like a table.

Note that the following will not work for all valid unicode property names (but neither will any of the other answers as far as I can tell).

const PATTERN = /[\^|\[|\.]([$|\w]+)/gu

function propValue(o, s) {
    const names = []
    for(let [, name] of [...s.matchAll(PATTERN)]) 
        names.push(name)
    return names.reduce((p, propName) => {
        if(!p.hasOwnProperty(propName)) 
            throw 'invalid property name'
        return p[propName]
    }, o)
}

let path = 'myObject.1._property2[0][0].$property3'
let o = {
    1: {
        _property2: [
            [{
                $property3: 'Hello World'
            }]
        ]
    }
}
console.log(propValue(o, path)) // 'Hello World'

With .Net WebRequest:

  public static string GetPublicIP()
    {
        string url = "http://checkip.dyndns.org";
        System.Net.WebRequest req = System.Net.WebRequest.Create(url);
        System.Net.WebResponse resp = req.GetResponse();
        System.IO.StreamReader sr = new System.IO.StreamReader(resp.GetResponseStream());
        string response = sr.ReadToEnd().Trim();
        string[] a = response.Split(':');
        string a2 = a[1].Substring(1);
        string[] a3 = a2.Split('<');
        string a4 = a3[0];
        return a4;
    }

I'm using VB 2010 .NET 4.0 and use the following:

Private Sub tbSecurity_KeyPress(sender As System.Object, e As System.EventArgs) Handles tbSecurity.KeyPress
    Dim tmp As System.Windows.Forms.KeyPressEventArgs = e
    If tmp.KeyChar = ChrW(Keys.Enter) Then
        MessageBox.Show("Enter key")
    Else
        MessageBox.Show(tmp.KeyChar)
    End If

End Sub

Works like a charm!

From your FirstActivity call the SecondActivity using startActivityForResult() method

For example:

int LAUNCH_SECOND_ACTIVITY = 1
Intent i = new Intent(this, SecondActivity.class);
startActivityForResult(i, LAUNCH_SECOND_ACTIVITY);

In your SecondActivity set the data which you want to return back to FirstActivity. If you don't want to return back, don't set any.

For example: In SecondActivity if you want to send back data:

Intent returnIntent = new Intent();
returnIntent.putExtra("result",result);
setResult(Activity.RESULT_OK,returnIntent);
finish();

If you don't want to return data:

Intent returnIntent = new Intent();
setResult(Activity.RESULT_CANCELED, returnIntent);
finish();

Now in your FirstActivity class write following code for the onActivityResult() method.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == LAUNCH_SECOND_ACTIVITY) {
        if(resultCode == Activity.RESULT_OK){
            String result=data.getStringExtra("result");
        }
        if (resultCode == Activity.RESULT_CANCELED) {
            //Write your code if there's no result
        }
    }
}//onActivityResult

Please disable js bundling and increase memory. That should fix it. I fixed mine by disabling js bundling.

If you have a 64-bit version of SQL Developer, but for some reason your default JDK is a 32-bit JDK (e.g. if you develop an Eclipse RCP application which requires a 32-bit JDK), then you have to set the value of the SetJavaHome property in the product.conf file to a 64-bit version of JDK in order to run the SQL Developer. For example:

SetJavaHome C:\Program Files\Java\jdk1.7.0_80

The product.conf file is in my case located in the following directory:

C:\Users\username\AppData\Roaming\sqldeveloper\1.0.0.0.0

The solution described above worked in my case. The solutions of @evgenyl and @FGreg did not work in my case.

In the SQL Server Management Studio, to find out details of the active transaction, execute following command

DBCC opentran()

You will get the detail of the active transaction, then from the SPID of the active transaction, get the detail about the SPID using following commands

exec sp_who2 <SPID>
exec sp_lock <SPID>

For example, if SPID is 69 then execute the command as

exec sp_who2 69
exec sp_lock 69

Now , you can kill that process using the following command

KILL 69

I hope this helps :)

I used a modified version of this answer - based on my experiences adding it to VS 2010:

1. Select Tools >> External Tools in Visual Studio
2. Click Add
3. Title: I use Visual Studio Command &Prompt
   • &P Makes P a alt-shortcut key (when menu active)
   • I originally used C, but that conflicts with the existing shortcut for Customize
4. Command: C:\Windows\System32\cmd.exe
5. Arguments: \k "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Tools\vsvars32.bat
   • /k keeps a secondary session active so the window doesn’t close on the .bat file
6. Initial Directory: I use $(ProjectDir) (from the dropdown)
7. Click OK.

Now you have command prompt access under the Tools Menu.

If you use random instead of * random your code not give any error

If you are a user of MacPorts, you may simply install usbutils

sudo port install usbutils

If you are not, this might be a good opportunity to install it, it has ports for several other useful linux tools.

Data validation drop down

There is a list option in Data validation. If this is combined with a VLOOKUP formula you would be able to convert the selected value into a number.

The steps in Excel 2010 are:

• Create your list with matching values.
• On the Data tab choose Data Validation
• The Data validation form will be displayed
• Set the Allow dropdown to List
• Set the Source range to the first part of your list
• Click on OK (User messages can be added if required)

In a cell enter a formula like this

=VLOOKUP(A2,$D$3:$E$5,2,FALSE)

which will return the matching value from the second part of your list.

Form control drop down

Alternatively, Form controls can be placed on a worksheet. They can be linked to a range and return the position number of the selected value to a specific cell.

The steps in Excel 2010 are:

• Create your list of data in a worksheet
• Click on the Developer tab and dropdown on the Insert option
• In the Form section choose Combo box or List box
• Use the mouse to draw the box on the worksheet
• Right click on the box and select Format control
• The Format control form will be displayed
• Click on the Control tab
• Set the Input range to your list of data
• Set the Cell link range to the cell where you want the number of the selected item to appear
• Click on OK

As of Spring 4.2.x, you can create custom mapping annotations, using @RequestMapping as a meta-annotation. So:

Is there a way to produce a "composite/inherited/aggregated" annotation with default values for consumes and produces, such that I could instead write something like:

@JSONRequestMapping(value = "/foo", method = RequestMethod.POST)

Yes, there is such a way. You can create a meta annotation like following:

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@RequestMapping(consumes = "application/json", produces = "application/json")
public @interface JsonRequestMapping {
    @AliasFor(annotation = RequestMapping.class, attribute = "value")
    String[] value() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "method")
    RequestMethod[] method() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "params")
    String[] params() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "headers")
    String[] headers() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "consumes")
    String[] consumes() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "produces")
    String[] produces() default {};
}

Then you can use the default settings or even override them as you want:

@JsonRequestMapping(method = POST)
public String defaultSettings() {
    return "Default settings";
}

@JsonRequestMapping(value = "/override", method = PUT, produces = "text/plain")
public String overrideSome(@RequestBody String json) {
    return json;
}

You can read more about AliasFor in spring's javadoc and github wiki.

function Parent() {_x000D_
  const [Name, setName] = useState("");_x000D_
  getChildChange = getChildChange.bind(this);_x000D_
  function getChildChange(value) {_x000D_
    setName(value);_x000D_
  }_x000D_
_x000D_
  return <div> {Name} :_x000D_
    <Child getChildChange={getChildChange} ></Child>_x000D_
  </div>_x000D_
}_x000D_
_x000D_
function Child(props) {_x000D_
  const [Name, setName] = useState("");_x000D_
  handleChange = handleChange.bind(this);_x000D_
  collectState = collectState.bind(this);_x000D_
  _x000D_
  function handleChange(ele) {_x000D_
    setName(ele.target.value);_x000D_
  }_x000D_
_x000D_
  function collectState() {_x000D_
    return Name;_x000D_
  }_x000D_
  _x000D_
   useEffect(() => {_x000D_
    props.getChildChange(collectState());_x000D_
   });_x000D_
_x000D_
  return (<div>_x000D_
    <input onChange={handleChange} value={Name}></input>_x000D_
  </div>);_x000D_
} 

useEffect act as componentDidMount, componentDidUpdate, so after updating state it will work

EDIT: The solution below is only for HTML "fragments" since html,head and body are removed. I guess the solution for this question is DOMParser's parseFromString() method.

For HTML fragments, the solutions listed here works for most HTML, however for certain cases it won't work.

For example try parsing <td>Test</td>. This one won't work on the div.innerHTML solution nor DOMParser.prototype.parseFromString nor range.createContextualFragment solution. The td tag goes missing and only the text remains.

Only jQuery handles that case well.

So the future solution (MS Edge 13+) is to use template tag:

function parseHTML(html) {
    var t = document.createElement('template');
    t.innerHTML = html;
    return t.content.cloneNode(true);
}

var documentFragment = parseHTML('<td>Test</td>');

For older browsers I have extracted jQuery's parseHTML() method into an independent gist - https://gist.github.com/Munawwar/6e6362dbdf77c7865a99

Love VonC's answer. Here's an easy version of it for beginners.

There is a git remote called origin which I am sure you are all aware of. Basically, you can add as many remotes to a git repo as you want. So, what we can do is introduce a new remote which is the original repo not the fork. I like to call it original

Let's add original repo's to our fork as a remote.

git remote add original https://git-repo/original/original.git

Now let's fetch the original repo to make sure we have the latest coded

git fetch original

As, VonC suggested, make sure we are on the master.

git checkout master

Now to bring our fork up to speed with the latest code on original repo, all we have to do is hard reset our master branch in accordance with the original remote.

git reset --hard original/master

And you are done :)

Declare the INNER class Thing as a static and it will work with no issues.

I remember I have the same issue with the inner class Dog when I declared it as class Dog { only. I got the same issue as you did. There were two solutions:

1- To declare the inner class Dog as static. Or

2- To move the inner class Dog to a new class by itself.

Here is the Example:

public class ReturnDemo {

public static void main(String[] args) {
    
    int z = ReturnDemo.calculate(10, 12);
    System.out.println("z = " + z);
    
    ReturnDemo.Dog dog = new Dog("Bosh", " Doggy");
    System.out.println( dog.getDog());
}


public static int calculate (int x, int y) {
    return x + y;
}

public void print( ) {
    System.out.println("void method");
    return;
}

public String getString() {
    return "Retrun String type value";
}


static class Dog {
    
private String breed;
private String name;

public Dog(String breed, String name) {
    super();
    this.breed = breed;
    this.name = name;
}

public Dog getDog() {
    // return Dog type;
    return this;
    
}

public String toString() {
    return "breed" + breed.concat("name: " + name);
}
}

}

If the tables have no common fields then there is no way to combine the data in any meaningful view. You would more likely end up with a view that contains duplicated data from both tables.

Here is the SOLUTION

If you get Response:

1. bash: python: command not found OR
2. bash: conda: command not found

To the following Commands: when you execute python or python -V conda or conda --version in your Git/Terminal window

Background: This is because you either

1. Installed Python in a location on your C Drive (C:) which is not directly in your program files folder.
2. Installed Python maybe on the D Drive (D:) and your computer by default searches for it on your C:
3. You have been told to go to your environment variables (located if you do a search for environment variables on your machines start menu) and change the "Path" variable on your computer and this still does not fix the problem.

Solution:

1. At the command prompt, paste this command export PATH="$PATH:/c/Python36". That will tell Windows where to find Python. (This assumes that you installed it in C:\Python36)

2. If you installed python on your D drive, paste this command export PATH="$PATH:/d/Python36".

3. Then at the command prompt, paste python or python -V and you will see the version of Python installed and now you should not get Python 3.6.5

4. Assuming that it worked correctly you will want to set up git bash so that it always knows where to find python. To do that, enter the following command: echo 'export PATH="$PATH:/d/Python36"' > .bashrc

Permanent Solution

5. Go to BASH RC Source File (located on C: / C Drive in “C:\Users\myname”)

6. Make sure your BASH RC Source File is receiving direction from your Bash Profile Source File, you can do this by making sure that your BASH RC Source File contains this line of code: source ~/.bash_profile

7. Go to BASH Profile Source File (located on C: / C Drive in “C:\Users\myname”)

8. Enter line: export PATH="$PATH:/D/PROGRAMMING/Applications/PYTHON/Python365" (assuming this is the location where Python version 3.6.5 is installed)

9. This should take care of the problem permanently. Now whenever you open your Git Bash Terminal Prompt and enter “python” or “python -V” it should return the python version

The Cause

Running your app in the Simulator before the previously running app has completely stopped.

The Fix

Wait until you see the Stop button become active again before running again.

(I'm using Xcode 4.2.1. This problem happened very frequently when I upgraded to OS X Lion).

Form controls are replaced elements in CSS.

10.3.4 Block-level, replaced elements in normal flow

The used value of 'width' is determined as for inline replaced elements. Then the rules for non-replaced block-level elements are applied to determine the margins.

So the form control should not be stretched to 100% width.

However, it should be centered. It looks like an ordinary bug in IE8. It centers the element if you set specific width:

<input type="submit" style="display: block; width:100px; margin: 0 auto;" />

Also try directly startup:

sqlplus /nolog
conn / as sysdba
startup

The method described here is very easy:

http://andreasglaser.net/post/2008/08/05/Extract-assembly-from-Global-Assembly-Cache-(GAC)-with-network-drive-mapping.aspx

Summary from Article:

• Map a Network Drive (Explorer -> Tools)
  • Map to \servername\folder (\\YourServer\C$\Windows\Assembly)
• No need for sharing if you are the Administrator
• Browse to the drive and extract your assembly

If it is in a form then it would be:

<form name="jojo">
<input name="jobtitle">
</form>

Then you would say in javascript:

var val= document.jojo.jobtitle.value

document.formname.elementname

Use below command to create a package.json file.

npm init 
npm init --yes or -y flag

[This method will generate a default package.json using information extracted from the current directory.]

Working with package.json

Here are 3 ways to do it

• 1 : On your MaterialApp set debugShowCheckedModeBanner to false.

   MaterialApp(
     debugShowCheckedModeBanner: false
   )
  

  The slow banner will also automatically be removed on release build.

• 2 : If you are using Android Studio, you can find the option in the Flutter Inspector tab --> More Actions.

• 3 : There is also another way for removing the "debug" banner from the flutter app. Now after new release there is no "debugShowCheckedModeBanner: false," code line in main. dart file. So I think these methods are effective:

  --> If you are using VS Code, then install "Dart DevTools" from extensions. After installation, you can easily find "Dart DevTools" text icon at the bottom of VS Code. When you click on that text icon, a link will be open in google chrome. From that link page, you can easily remove the banner by just tapping on the banner icon as shown.

For more info: How_to_remove_debug_banner_in_flutter_on_android_emulator

You can do it, but it requires two steps. Here's how:

git fetch <remote-git-url> <branch> && git cherry-pick FETCH_HEAD

Replace <remote-git-url> with the url or path to the repository you want cherry-pick from.

Replace <branch> with the branch or tag name you want to cherry-pick from the remote repository.

You can replace FETCH_HEAD with a git SHA from the branch.

Updated: modified based on @pkalinow's feedback.

Try this,

$('td').click(function(){
   var row_index = $(this).parent().index();
   var col_index = $(this).index();
});

If you need the index of table contain td then you can change it to

var row_index = $(this).parent('table').index(); 

This is what I used to use a csv file into an array. Couldn't get the above answers to work, but this worked for me.

$(document).ready(function() {
   "use strict";
    $.ajax({
        type: "GET",
        url: "../files/icd10List.csv",
        dataType: "text",
        success: function(data) {processData(data);}
     });
});

function processData(icd10Codes) {
    "use strict";
    var input = $.csv.toArrays(icd10Codes);
    $("#test").append(input);
}

Used the jQuery-CSV Plug-in linked above.

just use a reference:

Vec3b & color = image.at<Vec3b>(y,x);
color[2] = 13;

Yes, there is definitely a way to format numbers properly in javascript, for example:

var val=2489.8237

val.toFixed(3) //returns 2489.824 (round up)
val.toFixed(2) //returns 2489.82
val.toFixed(7) //returns 2489.8237000 (padding)

With the use of variablename.toFixed .

And there is another function toPrecision() . For more detail you also can visit

You might want to use jQuery's .addClass and .removeClass commands, and create two different classes for the states. This, to me, would be the best practice way of doing it.

I got this problem while launching a VS2013 32-bit console application in powershell, launching it in cmd did not issue this problem.

Follow the steps mentioned for using support ActionBar in Android Studio(0.4.2) :

Download the Android Support Repository from Android SDK Manager, SDK Manager icon will be available on Android Studio tool bar (or Tools -> Android -> SDK Manager).

After download you will find your Support repository here

$SDK_DIR\extras\android\m2repository\com\android\support\appcompat-v7

Open your main module's build.gradle file and add following dependency for using action bar in lower API level

dependencies {
    compile 'com.android.support:appcompat-v7:+'
}

Sync your project with gradle using the tiny Gradle icon available in toolbar (or Tools -> Android -> Sync Project With Gradle Files).

There is some issue going on with Android Studio 0.4.2 so check this as well if you face any issue while importing classes in code.

Import Google Play Services library in Android Studio

If Required follow the steps as well :

• Exit Android Studio
• Delete all the .iml files and files inside .idea folder from your project
• Relaunch Android Studio and wait till the project synced completely with gradle. If it shows an error in Event Log with import option click on Import Project.

This is bug in Android Studio 0.4.2 and fixed for Android Studio 0.4.3 release.

Better way to do this use custom dialog and customize according your needs here is custom dialog example.....

public class CustomDialogUI {
Dialog dialog;
Vibrator vib;
RelativeLayout rl;

@SuppressWarnings("static-access")
public void dialog(final Context context, String title, String message,
        final Runnable task) {
    dialog = new Dialog(context);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.custom);
    dialog.setCancelable(false);
    TextView m = (TextView) dialog.findViewById(R.id.message);
    TextView t = (TextView) dialog.findViewById(R.id.title);
    final Button n = (Button) dialog.findViewById(R.id.button2);
    final Button p = (Button) dialog.findViewById(R.id.next_button);
    rl = (RelativeLayout) dialog.findViewById(R.id.rlmain);
    t.setText(bold(title));
    m.setText(message);
    dialog.show();
    n.setText(bold("Close"));
    p.setText(bold("Ok"));
    // color(context,rl);
    vib = (Vibrator) context.getSystemService(context.VIBRATOR_SERVICE);
    n.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {
            vib.vibrate(15);
            dialog.dismiss();
        }
    });
    p.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {
            vib.vibrate(20);
            dialog.dismiss();
            task.run();
        }
    });
}
 //customize text style bold italic....
public SpannableString bold(String s) {
    SpannableString spanString = new SpannableString(s);
    spanString.setSpan(new StyleSpan(Typeface.BOLD), 0,
            spanString.length(), 0);
    spanString.setSpan(new UnderlineSpan(), 0, spanString.length(), 0);
    // spanString.setSpan(new StyleSpan(Typeface.ITALIC), 0,
    // spanString.length(), 0);
    return spanString;
}

}

The latest build of the sublime even allows the direct command instead of double quotes. Try the below code for the build system

{
    "cmd" : ["gcc $file_name -o ${file_base_name} && ./${file_base_name}"],
    "selector" : "source.c",
    "shell": true,
    "working_dir" : "$file_path",
}

Just as a follow up for anyone still running into this – I had added the ServicePointManager.SecurityProfile options as noted in the solution:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;

And yet I continued to get the same “The request was aborted: Could not create SSL/TLS secure channel” error. I was attempting to connect to some older voice servers with HTTPS SOAP API interfaces (i.e. voice mail, IP phone systems etc… installed years ago). These only support SSL3 connections as they were last updated years ago.

One would think including SSl3 in the list of SecurityProtocols would do the trick here, but it didn’t. The only way I could force the connection was to include ONLY the Ssl3 protocol and no others:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;

Then the connection goes through – seems like a bug to me but this didn’t start throwing errors until recently on tools I provide for these servers that have been out there for years – I believe Microsoft has started rolling out system changes that have updated this behavior to force TLS connections unless there is no other alternative.

Anyway – if you’re still running into this against some old sites/servers, it’s worth giving it a try.

I tried the answer from LBushkin and it worked great, but it won't work for null values and nullable fields. So I've changed it to this:

propertyName= "Latitude";
PropertyInfo propertyInfo = ship.GetType().GetProperty(propertyName);
if (propertyInfo != null)
{
     Type t = Nullable.GetUnderlyingType(propertyInfo.PropertyType) ?? propertyInfo.PropertyType;
     object safeValue = (value == null) ? null : Convert.ChangeType(value, t);
     propertyInfo.SetValue(ship, safeValue, null);
}

Not sure if this is already answered, but if you want only a table in a figure window, then you can hide the axes:

fig, ax = plt.subplots()

# Hide axes
ax.xaxis.set_visible(False) 
ax.yaxis.set_visible(False)

# Table from Ed Smith answer
clust_data = np.random.random((10,3))
collabel=("col 1", "col 2", "col 3")
ax.table(cellText=clust_data,colLabels=collabel,loc='center')

I wanted a way to do this without using an extra module. First turn list to string, then append to an array:

dataset_list = ''.join(input_list)
dataset_array = []
for item in dataset_list.split(';'): # comma, or other
    dataset_array.append(item)

Make use of Parameter Grouping (Laravel 4.2). For your example, it'd be something like this:

Model::where(function ($query) {
    $query->where('a', '=', 1)
          ->orWhere('b', '=', 1);
})->where(function ($query) {
    $query->where('c', '=', 1)
          ->orWhere('d', '=', 1);
});

While AngularJS allows you to get a hand on a click event (and thus a target of it) with the following syntax (note the $event argument to the setMaster function; documentation here: http://docs.angularjs.org/api/ng.directive:ngClick):

function AdminController($scope) {    
  $scope.setMaster = function(obj, $event){
    console.log($event.target);
  }
}

this is not very angular-way of solving this problem. With AngularJS the focus is on the model manipulation. One would mutate a model and let AngularJS figure out rendering.

The AngularJS-way of solving this problem (without using jQuery and without the need to pass the $event argument) would be:

<div ng-controller="AdminController">
    <ul class="list-holder">
        <li ng-repeat="section in sections" ng-class="{active : isSelected(section)}">
            <a ng-click="setMaster(section)">{{section.name}}</a>
        </li>
    </ul>
    <hr>
    {{selected | json}}
</div>

where methods in the controller would look like this:

$scope.setMaster = function(section) {
    $scope.selected = section;
}

$scope.isSelected = function(section) {
    return $scope.selected === section;
}

Here is the complete jsFiddle: http://jsfiddle.net/pkozlowski_opensource/WXJ3p/15/

When I use Vladimir's CALayer solution, and on top of the view I have an animation, like a modal UINavigationController dismissing, I see a lot of glitches happening and having drawing performance issues.

So, another way to achieve this, but without the glitches and performance loss, is to make a custom UIView and implement the drawRect message like so:

- (void)drawRect:(CGRect)rect
{
    CGContextRef contextRef = UIGraphicsGetCurrentContext();
    CGContextSetLineWidth(contextRef, 1);
    CGContextSetRGBStrokeColor(contextRef, 255.0, 255.0, 255.0, 1.0);
    CGContextStrokeRect(contextRef, rect);    
}

Late to the trim party

Features:
1. Trim the beginning quickly, as in a number of other answers.
2. After going to the end, trimming the right with only 1 test per loop. Like @jfm3, but works for an all white-space string)
3. To avoid undefined behavior when char is a signed char, cast *s to unsigned char.

Character handling "In all cases the argument is an int, the value of which shall be representable as an unsigned char or shall equal the value of the macro EOF. If the argument has any other value, the behavior is undefined." C11 §7.4 1

#include <ctype.h>

// Return a pointer to the trimmed string
char *string_trim_inplace(char *s) {
  while (isspace((unsigned char) *s)) s++;
  if (*s) {
    char *p = s;
    while (*p) p++;
    while (isspace((unsigned char) *(--p)));
    p[1] = '\0';
  }

  // If desired, shift the trimmed string

  return s;
}

@chqrlie commented the above does not shift the trimmed string. To do so....

// Return a pointer to the (shifted) trimmed string
char *string_trim_inplace(char *s) {
  char *original = s;
  size_t len = 0;

  while (isspace((unsigned char) *s)) {
    s++;
  } 
  if (*s) {
    char *p = s;
    while (*p) p++;
    while (isspace((unsigned char) *(--p)));
    p[1] = '\0';
    // len = (size_t) (p - s);   // older errant code
    len = (size_t) (p - s + 1);  // Thanks to @theriver
  }

  return (s == original) ? s : memmove(original, s, len + 1);
}

compare() is equivalent to strcmp(). == is simple equality checking. compare() therefore returns an int, == is a boolean.

I think you've actually got a wider confusion here.

The initial error is that you're trying to call split on the whole list of lines, and you can't split a list of strings, only a string. So, you need to split each line, not the whole thing.

And then you're doing for points in Type, and expecting each such points to give you a new x and y. But that isn't going to happen. Types is just two values, x and y, so first points will be x, and then points will be y, and then you'll be done. So, again, you need to loop over each line and get the x and y values from each line, not loop over a single Types from a single line.

So, everything has to go inside a loop over every line in the file, and do the split into x and y once for each line. Like this:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    readfile = open(filename, "r")

    for line in readfile:
        Type = line.split(",")
        x = Type[1]
        y = Type[2]
        print(x,y)

getQuakeData()

As a side note, you really should close the file, ideally with a with statement, but I'll get to that at the end.

Interestingly, the problem here isn't that you're being too much of a newbie, but that you're trying to solve the problem in the same abstract way an expert would, and just don't know the details yet. This is completely doable; you just have to be explicit about mapping the functionality, rather than just doing it implicitly. Something like this:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    readfile = open(filename, "r")
    readlines = readfile.readlines()
    Types = [line.split(",") for line in readlines]
    xs = [Type[1] for Type in Types]
    ys = [Type[2] for Type in Types]
    for x, y in zip(xs, ys):
        print(x,y)

getQuakeData()

Or, a better way to write that might be:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    # Use with to make sure the file gets closed
    with open(filename, "r") as readfile:
        # no need for readlines; the file is already an iterable of lines
        # also, using generator expressions means no extra copies
        types = (line.split(",") for line in readfile)
        # iterate tuples, instead of two separate iterables, so no need for zip
        xys = ((type[1], type[2]) for type in types)
        for x, y in xys:
            print(x,y)

getQuakeData()

Finally, you may want to take a look at NumPy and Pandas, libraries which do give you a way to implicitly map functionality over a whole array or frame of data almost the same way you were trying to.

I believe that your problem is due to the fact that - is not a word character. Thus, the word boundary will match after the -, and so will not capture it. Word boundaries match before the first and after the last word characters in a string, as well as any place where before it is a word character or non-word character, and after it is the opposite. Also note that word boundary is a zero-width match.

One possible alternative is

(?:(?:^|\s)-?)\d+\b

This will match any numbers starting with a space character and an optional dash, and ending at a word boundary. It will also match a number starting at the beginning of the string.

Because C will promote floats to doubles for functions that take variable arguments. Pointers aren't promoted to anything, so you should be using %lf, %lg or %le (or %la in C99) to read in doubles.
